The following is a list of characters of Monk, an American comedy-drama detective mystery television series, created by Andy Breckman and starring Tony Shalhoub as the titular character, Adrian Monk. Except for two changes, the principal cast of the series remained consistent. For the first three seasons Sharona Fleming was Monk's assistant. She left to re-marry her ex-husband in the middle of season three. She was replaced by Natalie Teeger, in the episode "Mr. Monk and the Red Herring", and remained Monk's assistant for the remainder of the series. Stanley Kamel, who portrayed Monk's therapist, Dr. Charles Kroger, died of a heart attack in April 2008, during the production hiatus in between seasons six and seven. That character was replaced by Dr. Neven Bell (Hector Elizondo), who remained for the final two seasons.
Although their names appeared in the opening credits, Ted Levine and Jason Gray-Stanford had occasional absences from the series. Thus, Tony Shalhoub was the only cast member to appear in all 125 episodes.

Secondary characters 
Julie Teeger 
|First appearance||"Mr. Monk and the Red Herring"|
|Last appearance||"Mr. Monk and the End - Part I"
"Mr. Monk and the End - Part II" (flashback only)
|Portrayed by||Emmy Clarke
Julie Teeger (played by Emmy Clarke) is Natalie's teenage daughter. She appears in many episodes of the show, usually in minor roles. Like her mother, Julie is introduced during the season three episode "Mr. Monk and the Red Herring". Julie bonds with Monk after he rescues her pet fish. In that episode, Julie is 11 years old.
Julie plays a key role in the season four episode "Mr. Monk Goes to a Fashion Show", when Julian Hodge (Malcolm McDowell) invites her to participate in his fashion show, despite her young age. Natalie is reluctant at first but then gives in. When Monk discovers that Hodge murdered models Clea Vance and Natasia Zorelle, Natalie forbids her daughter to participate in the show, causing Julie to run away from home to be in the show.
In the season five episode "Mr. Monk and the Really, Really Dead Guy", Julie teaches Monk how to use her computer. When he brings it to the station while the FBI is trying to trace a call from a killer, he plugs it in along with the other computers. In the middle of the meeting, Monk intercepts an email from one of Julie's friends, and responds to it. Wires get crossed, and a short time later, a S.W.A.T. team storms a house, scaring a slumber party of innocent teens, including Julie, near to death.
In the season five episode "Mr. Monk and the Big Game", Julie and her friends on the high school basketball team hire Monk to investigate the death of their basketball coach, Lynn Hayden, after she is found electrocuted and killed in the locker room. Natalie temporarily coaches the team with Monk as her assistant.
Julie plays another critical role in season six episode "Mr. Monk and the Birds and the Bees", in which Monk gives her "the talk" after she starts dating Clay Bridges. Clay later reveals that he was paid by Julie's (fictitious) Aunt Karen to go out with her. "Karen" is revealed to be the girlfriend of sports agent Rob Sherman, who killed his wife and career burglar Dewey Jordan in a staged break-in. He has his girlfriend pose as Julie's aunt because he saw a T-shirt with a photo of Julie and her previous boyfriend Tim Sussman, in which he and Dewey converse in the background. The episode gives Julie an integral role.
In the season six episode "Mr. Monk and the Three Julies", Julie receives her driver's license. After two other women with the name 'Julie Teeger' are killed, Natalie's Julie becomes the only person with this name within 1,000 miles. In the same episode, it is revealed that Julie was named for Mitch's aunt, who was one of the first female war correspondents in Vietnam.
Julie is seventeen years old by the time of the season seven episode "Mr. Monk Is Underwater". Trying to become an actress during the season eight episode "Mr. Monk and the Critic", Julie's beautiful voice is the key to proving that theater critic John Hannigan snuck out and killed his girlfriend Callie Esterhaus during a theater performance.
Julie also appears in the tie-in series of novels by Lee Goldberg. Her role in the books are minor, but she occasionally, knowingly or not, gives Monk crucial information that is key to solving a murder case:
- In Mr. Monk Goes to the Firehouse, when a firehouse dog named Sparky is murdered, Julie hires Monk to investigate pro bono.
- In Mr. Monk and the Blue Flu, Julie's attention to brands and fashion gives Monk a crucial clue in tracking down a serial killer.
- In Mr. Monk and the Two Assistants, Julie breaks her wrist during a soccer game and subsequently pays to have a local pizzeria advertise on her cast. Monk uses this to prove that mystery writer Ian Ludlow killed a local shoe salesman and tried to frame Natalie for it.
Charles Kroger 
|Dr. Charles Kroger|
|First appearance||"Mr. Monk and the Candidate (Part One)"|
|Last appearance||"Mr. Monk Paints His Masterpiece"
"Mr. Monk and the End - Part II"
|Portrayed by||Stanley Kamel
Dr. Kroger serves as a critical pillar of emotional support for Monk. While he engages in routine talk therapy, he does not prescribe medication. Adrian avoids medications, for when he does, things can go badly. In "Mr. Monk Takes His Medicine", Dr. Kroger prescribes Dioxynl, which successfully relieves Monk's phobias while also impairing his detective skills.
Dr. Kroger is instrumental in trying to get Monk reinstated as a detective, all while discussing his problems and progress as a person. In the novel Mr. Monk and the Blue Flu, Natalie describes Dr. Kroger as relaxed towards everything: she notes that she could easily walk into his office with a monkey on her head and a ratchet in her chest, and he would not be the least bit disturbed.
Most of Dr. Kroger's scenes help move Monk's character forward. Similarly, Dr. Kroger also (usually unintentionally) helps Monk solve cases. In the season five episode "Mr. Monk Gets a New Shrink", he temporarily retires when he finds his cleaning lady Teresa Mueller stabbed and killed in his office, and the police believe that one of his patients is responsible. However, Monk soon finds that the cleaning lady was killed by drug trafficker Francis Merrigan, who also owns an office in Dr. Kroger's building.
Dr. Kroger is also the subject of an ongoing feud between Monk and Harold Krenshaw, another patient with similar problems. While very forgiving, even he has to get fed up with Monk from time to time, most heavily demonstrated in "Mr. Monk and the Sleeping Suspect", when Dr. Kroger returns from vacationing in Costa Rica and sees Monk standing outside his home. Dr. Kroger instructs the cab driver to keep driving and keeps his head low to avoid Monk. In "Mr. Monk and the Garbage Strike", when the city stops collecting garbage, Monk is so desperate that he actually mails his garbage to Dr. Kroger's house. When Dr. Kroger confronts him about this, Monk denies it until Dr. Kroger points out that the garbage has been sorted according to color and food groups and has Monk's handwriting on it.
In several cases Dr. Kroger is the only person capable of getting through to Monk during difficult situations, such as when Monk is brainwashed by Ralph Roberts (Howie Mandel) in the season 6 episode "Mr. Monk Joins a Cult".
It is revealed in the season three episode "Mr. Monk and the Election" that Dr. Kroger is married, had a first wife, has children, and is Jewish. In the first episode of season five, "Mr. Monk and the Actor", Monk wants to take up the entire week with therapy, but Dr. Kroger says he does not like working on the weekends so he can spend time with family. In "Mr. Monk Gets a New Shrink", it is revealed that he has a wife, Madeline, and a rebellious adolescent son, Troy, who denies that he is their child.
The season seven episode "Mr. Monk Buys a House" is dedicated to Stanley Kamel's memory.
Troy Kroger 
Troy Kroger (portrayed by Cody McMains) is the son of Dr. Kroger, with whom he has a stormy relationship. The season five episode "Mr. Monk Gets a New Shrink" reveals that Charles has taken three paternity tests at the "request" of his son. Troy calls his parents by their first names and it is revealed that Randy had arrested him at least once before. He responds "no" when Randy asks him if he's stayed out of trouble.
Troy later appears in the season six episode "Mr. Monk and the Buried Treasure". While skateboarding with his friends Ridley and Pez, one of their skateboards hits the side of a parked car. When they go to apologize to Tony Gamelobo, the driver, and find him dead from a heart attack, they find a map in the back of his car that leads to what they think is buried treasure. Troy and his friends ask Monk to help them, saying it is a school project. Monk agrees, and they eventually find it at a quarry. Monk, however, later discovers he's been tricked when he learns that Tony Gamelobo was one of the robbers in a bank robbery that happened the day before he was discovered. When he and Troy return to the quarry in question, a bulldozer driven by crooked bank manager Steven Connolly buries them alive, and Monk and Troy nearly suffocate. After they are rescued, it becomes clear that Troy has a better relationship with his father, and is planning to follow his father and study psychology in college. While buried alive, Troy also keeps Monk calm while they wait for help.
Neven Bell 
|First appearance||"Mr. Monk Buys a House"|
|Last appearance||"Mr. Monk and the End - Part II"|
|Portrayed by||Héctor Elizondo (2008–2009)|
Though Monk is initially skeptical, Dr. Bell wins his confidence though several small gestures: he begins the appointment at the exact second it is scheduled, supplies Monk with his favorite bottled water, wipes during their introductory handshake, and displays a painting in his office which previously belonged to the late Dr. Kroger.
Additionally, before the first session, Natalie points out that Dr. Bell's first name is a palindrome as a comfort to Monk. Monk points out that it is not a "perfect" palindrome, since the first "N" is capitalized. Dr. Bell also uses his past baseball experiences when talking with Monk in "Mr. Monk Takes the Stand".
Dr. Bell's character has a more considerably constructed background, in sharp contrast to Dr. Kroger. In "Mr. Monk Buys a House", Natalie describes Dr. Bell as a psychiatric genius, and mentions that he has written five books and teaches at Stanford University. Later, in "Mr. Monk Gets Lotto Fever", when Monk confides how he loathes Natalie for getting more attention than him, Dr. Bell is forced to admit to being a diva after writing an unsuccessful book on body language. The episode "Mr. Monk Fights City Hall" reveals that Dr. Bell served on the city council in Tulsa, Oklahoma, but he got bored with the job and started sending his secretary as his proxy.
Dale "The Whale" Biederbeck 
|Dale J. Biederbeck III|
Adam Arkin as Dale the Whale
|First appearance||"Mr. Monk Meets Dale the Whale"|
|Last appearance||"Mr. Monk Is On the Run (Part Two)"|
|Portrayed by||Adam Arkin
|Aliases||Dale "The Whale" Biederbeck|
Dale J. Biederbeck III, better known as Dale "The Whale" because of his size, is a recurring villain, appearing in three episodes. In the first season, he is played by Adam Arkin, in the second by Tim Curry, and in the sixth by Ray Porter, all of them wearing fat suits.
Dale is a very rich and well-connected financier, who is arrogant, brilliant, and ruthless. Monk claims that Biederbeck owns "half the city" of San Francisco, and has an option on the other half. He gets his nickname from his morbid obesity.
In "Mr. Monk Meets Dale the Whale", Dr. Christiaan Vezza, Dale's physician, reveals that when he first moved into his apartment, he weighed 400 pounds and could occasionally see his toes. But after his mother died, he started binging, ordering everything on a restaurant's menu. He topped out at 900 pounds about 11 years before the events of the episode, and has been bedridden ever since. In his first and second appearances, he weighs upwards of 800 pounds, or 360 kilograms, and is unable to leave his bed. By his third appearance in "Mr. Monk Is On the Run (Part Two)", he has lost just enough weight to get around in a wheelchair.
In his first appearance, "Mr. Monk Meets Dale the Whale", Biederbeck is the primary suspect in the slaying of Catherine Lavinio, a superior court judge who issued a costly antitrust ruling against him. Several clues point to him, but this seems impossible because he is incapable of leaving his bedroom. Monk discovers that he ordered Vezza to murder the judge and implicate Biederbeck. It is also revealed in this episode that Monk harbors a severe hatred of Biederbeck, who sued Trudy and her newspaper after her article profiled him as "the Genghis Khan of world finance".
Biederbeck goes to extreme lengths to avoid publicity, to the point of buying newspaper companies just so that they would not print his name. The first twenty numbers on his speed-dial are all lawyers. He pursues the drawn-out libel suit just to torment Trudy. Legal costs force the Monks to sell their first home, which Biederbeck purchased to store his collection of pornography. Because Trudy is killed a short time later, Monk feels that Biederbeck stole one of the last years of her life.
Biederbeck reappears in the season two finale "Mr. Monk Goes to Jail". Although convicted of murder, he is adjusting to life in prison quite easily. He has an inmate to act as his personal servant, luxurious furniture, a TV, and just about everything one would not normally find in a prison environment, except a window. After condemned prisoner Ray Kaspo is poisoned less than an hour before his execution, suspicion falls on Biederbeck, to whom Kaspo owed $1,200. Monk knows that Biederbeck would not kill anyone over such a petty sum: Biederbeck laughs, "I wouldn't bend down to pick up $1,200, even if I could". Until the killer is caught, the prison refuses to install a window in Dale's cell. He offers Monk a deal: find the killer, and Biederbeck will share what he knows about Trudy's murder.
Even though Sharona tells him not to, Monk takes the case on the off-chance that Dale is telling the truth. After Monk finds that prison librarian Sylvia Fairborn killed Kaspo, Dale reveals that Trudy was, contrary to Monk's belief, indeed the intended victim of the car bomb. He also states that Monk should look for a man named Warrick Tennyson who can be found in Manhattan, New York. This gives Monk his first real lead on Trudy's death. The episode ends on an ominous note, as Biederbeck watches Monk's plane depart for New York through his newly installed window and smiles, "Bon voyage, Mr. Monk."
In the third season premiere, Monk finds Tennyson, who confesses to being hired to kill Trudy, and identifies the man who hired him as having a six-fingered hand. To Sharona's and Monk's surprise, Biederbeck told the truth.
The reason becomes clear in the two-part episode "Mr. Monk Is On the Run", when Monk is framed for murder of Frank Nunn, the six-fingered man who hired Tennyson. Dale is revealed to be the mastermind of the plot, and of a simultaneous plot to assassinate the state governor. The lieutenant governor, who is on Dale's payroll, would then pardon Dale, completing his revenge by setting him free and jailing Monk. The detective foils Dale's plan, and John Rollins, the Angel County sheriff whom Dale recruited to frame Monk, turns state's evidence. As a result, all of Dale's privileges are revoked. His custom bed, telephone, and laptop are confiscated, and his window is removed. His special meal deliveries and manicure appointments are cancelled, and he is reduced to sleeping in a cramped bunk bed, with only a wheelchair and prison food to distract him.
Biederbeck also makes a brief appearance in the 2008 novel Mr. Monk Goes to Germany by Lee Goldberg. Monk telephones Biederbeck from Germany when he suspects that one of Dr. Kroger's colleagues, a psychiatrist with a six-fingered hand named Dr. Martin Rahner, is the man who killed Trudy. Since the doctor was giving a lecture at Berkeley around the same time that Trudy was killed, thanks to a grant from one of Biederbeck's foundations, Monk suspects Biederbeck of being the killer. Biederbeck smugly refuses to confirm or deny Monk's suspicions, but later Monk proves that the doctor is not Trudy's killer.
Dale "The Whale" is frequently compared to Professor Moriarty, Sherlock Holmes's nemesis, even including his nickname ("The Genghis Khan of World Finance" for Dale, and "The Napoleon of Crime" for Moriarty), further echoing on the analogue of the four main characters to Sherlock Holmes characters.
Benjy Fleming 
|First appearance||"Mr. Monk and the Candidate"|
|Last appearance||"Mr. Monk and the Employee of the Month"|
|Portrayed by||Max Morrow
(maternal grandfather; deceased)
Benjamin "Benjy" Fleming is Sharona's son. He is played by Kane Ritchotte in the pilot, season two, and the first half of season three, and by Max Morrow in the rest of season one. It was necessary to have two actors play the role because Ritchotte lives on the west coast, while the pilot was filmed (in Vancouver) and the second and third season (in Los Angeles). Morrow lives on the east coast, where the remainder of season one was filmed (in Toronto). Benjy eventually returns to New Jersey with his mother to reunite with his father, Trevor.
Over Benjy's tenure, Monk bonds with him but has his problems in relating since he never did most of the things that kids do while growing up. As a result, he is clueless in giving Benjy a pep talk about baseball in "Mr. Monk Goes to the Ballgame", as Benjy has to show him how to hold a bat. In "Mr. Monk Meets the Playboy", Sharona tells him of her less than reputable past. This is nearly revealed by playboy Dexter Larsen if Monk had persisted in his current homicide investigation. She confesses, knowing Benjy would be open to ridicule and perhaps lose respect for her. Benjy reassures her that he can handle it.
He is in little league in "Mr. Monk Goes to the Ballgame". He is a sixth-grader and wants to be a writer in "Mr. Monk Takes a Vacation", in which he witnesses cleaning maids murdering one of their own while pulling off an insider trading scheme.
His first appearance in any Monk-related material after he and Sharona left the television show is in the Lee Goldberg novel Mr. Monk and the Two Assistants, where Sharona returns to San Francisco because Trevor has been accused of murder. Since Sharona is working as a nurse, Benjy is living with her sister Gail. Over the course of the novel, Benjy develops a friendship with Julie Teeger. Benjy and his mother are mentioned in "Mr. Monk Is On the Run (Part Two)", having sent flowers for the "deceased" Monk and flying in to attend his "funeral".
In the season eight episode "Mr. Monk and Sharona", Sharona mentions that Benjy is making plans to attend college, and he plans on using money from her lawsuit against a country club for the death of her uncle, Howard Fleming. However, Monk thinks that Howard's death was foul play, irritating cash-strapped Sharona. At the end of the episode, Sharona trips and breaks her arm on one of the country club's steps, meaning she will get the money after all.
Trudy Monk 
|First appearance||"Mr. Monk and the Candidate"|
|Last appearance||"Mr. Monk and the End - Part II"|
|Portrayed by||Stellina Rusich
(2006 college flashbacks)
Jack Monk, Sr.
Jack Monk, Jr.
(married at time of death)
Trudy Anne Ellison Monk is Adrian's beloved deceased wife, played by Stellina Rusich in the first two seasons and Melora Hardin after the third season. In the season five episode "Mr. Monk and the Class Reunion", a younger Trudy is portrayed in a flashback by Lindy Newton. Adrian's attempt to solve the case of her murder is the show's longest-running plot arc.
Trudy Monk was born in Los Angeles in 1962 to Dwight and Marcia Ellison. She attended the Ashton Preparatory School and graduated valedictorian in 1977, at the age of 15. She did not date very much while there, expecting to know who the right man would be once she found him. Trudy and Adrian met during his senior year at UC Berkeley (episode "Mr. Monk and the Class Reunion"). They married on August 8, 1990.
In 1993, Trudy was involved in a lawsuit with the financier Dale "The Whale" Biederbeck because she referred to him as the "Genghis Khan of Finance". Dale was unable to win the lawsuit, but the Monks were forced to sell their house paying for their lawyer. Adrian harbors an intense hatred for Dale because of the pain he caused Trudy, saying that he stole a year of her life. Dale remains an important adversary of Adrian's, especially when it is revealed that he was hiding something he knew about Trudy's death.
In Adrian's words, Trudy "enjoyed poetry, was often barefoot, and kept every promise she ever made". Adrian offers a glimpse into her mindset (in "Mr. Monk Takes Manhattan") by turning Warrick Tennyson's morphine back on after he had turned it off claiming Trudy would have wanted him to.
Trudy Monk was murdered on a snowy December 14, 1997 with a car bomb, made of approximately three pounds of plastic explosives, powered by ten 20 volt magnesium batteries that was planted under the front seat and remotely detonated by a cell phone. She was on an errand to get cough medicine for Adrian's brother, Ambrose. Ambrose blames himself for Trudy's death, and his guilt led to a seven-year rift between the brothers.
While having a temporary relapse (in "Mr. Monk Can't See a Thing"), Adrian mentions that Trudy lived for 20 minutes after the bomb went off. Her last words to a paramedic were "bread and butter", a message to Adrian meaning that she would never leave him, as this was something she always told her husband when they had to temporarily let go of each other for some reason or another.
The bomb was built by Warrick Tennyson. Tennyson mentions (in "Mr. Monk Takes Manhattan") that he did not recognize the man who hired him, but remembers that there were six fingers on his right hand. From the time of Trudy's death until the end of the season two, Monk believes all along that he was the intended target, with Trudy being an innocent victim. The intense guilt contributed to and intensified his nervous breakdown, his obsessive-compulsive manifestations, and his bizarre phobias.
Dale reveals (in "Mr. Monk Goes to Jail") that the car bomb was actually intended for her, not him. Discovering that Trudy was the true target, Adrian is seen to be visibly affected by this piece of news.
Adrian attempts (in "Mr. Monk Bumps His Head") to find this six-fingered man by purchasing a picture of him. The picture turns out to be doctored, leading to Teddy Mulligan, the seller, knocking Monk unconscious and sending him to a town in Wyoming, in turn causing Monk to uncover the murder of a waitress while forgetting his own name.
Natalie overhears a woman (in "Mr. Monk and Mrs. Monk") who looks like Trudy say that she faked her own death to protect Adrian. Adrian begins to believe this might be true, but in the end, it turns out that this woman is an actress who has attempted to pass herself off as the real Trudy in order to get the key to Trudy's old storage unit.
Adrian (in "Mr. Monk Is Up All Night") sees a Brazilian woman named Maria Cordova, whom he chases for several blocks for no apparent reason. It is later revealed that the reason he was drawn to her is that she received a cornea transplant from an organ donor, who turned out to be Trudy.
During the season six finale ("Mr. Monk Is On the Run"), Adrian finds the six-fingered man, named Frank Nunn, but unfortunately he is shot and killed by John Rollins, a corrupt Angel County sheriff recruited by Dale in a plot to incriminate Adrian. By the end of the episode, Adrian confronts Dale, telling him that the police searched Nunn's house after he died. The police discovered some old letters in which Nunn talked about killing Trudy and also mentioned that he was hired by a man named "The Judge". Adrian believes Dale knows the identity of "The Judge", but so far, Dale had not revealed any further information.
Monk discovers (in "Mr. Monk and the End Part 1") that Trudy had left him a videotape, containing a message stating that she wanted him to watch in case harm were to befall her. Later, Monk and Natalie watch the videotape, which reveals that Trudy had a child with her professor, Ethan Rickover, who is now a judge. Rickover hid the baby from Trudy by claiming that she died nine minutes after birth. Then, Monk learns that, in fact, Rickover had saved the baby girl who is now a 26-year-old movie critic named Molly who he re-connects with and grows to love.
Harold Krenshaw 
|First appearance||"Mr. Monk and the Girl Who Cried Wolf"|
|Last appearance||"Mr. Monk Goes to Group Therapy"
"Mr. Monk and the End - Part II (flashback only)
|Portrayed by||Tim Bagley
|Occupation||School Board Member, City Council Member|
|Family||Cousin Joey (Cousin)
Mrs. Krenshaw (Wife)
Jimmy Krenshaw (Son)
Harold J. Krenshaw (Tim Bagley) is another patient of Dr. Kroger and later Dr. Bell who also suffers from obsessive-compulsive disorder. Despite sharing the same disorder, Monk and Harold are constantly at odds, mostly over which of them is liked better by Dr. Kroger, or which of them have made more progress in overcoming their various problems. Even then, Monk has made clear that Harold has more psychological problems than him: Monk suffers from pure OCD, but Harold also suffers from acute paranoia and narcissism (in "Mr. Monk and the Daredevil," Monk recalls that Harold went vertigo when Dr. Kroger put thicker carpet in his office). As a result, he deludes himself that everyone is out to get him, either because of his importance in the scheme of things, or because he inspires outrageous jealousy in everyone else. He often takes great pleasure in "getting" other people before they get him, especially Monk. Harold is married and has a son, Jimmy.
Harold's first appearance was brief, in a scene in the season three episode "Mr. Monk and the Girl Who Cried Wolf" when he and Monk bicker over the arrangement of magazines in Dr. Kroger's waiting room. Monk prefers the magazines to be arranged in two vertical rows of three. Harold prefers the horizontal top row to have three, the middle row have two, and the bottom row have one (in an arrangement similar to the style of bowling pins), and wants them arranged by type, instead of in alphabetical order.
In the season five episode "Mr. Monk Gets a New Shrink", when Adrian and Dr. Kroger are being held hostage in the back of Francis Merrigan's truck, Harold, who had followed the truck, is the one who alerts the police to their whereabouts. When Merrigan shoots at Dr. Kroger with a Vektor CP1 pistol, Harold takes a bullet in the chest to save Dr. Kroger's life, telling Adrian to "beat that."
In the season six episode "Mr. Monk and the Daredevil", Harold eclipses a jealous Monk in fame when the public at large believes him to be a notorious human fly known only as the Frisco Fly. In reality, Harold was dropped into the role by his cousin Joey who was trying to kill him over an inheritance from their dying uncle. Unaware of the murder plot, Harold went along with the charade because he loved the public attention, getting a golden opportunity to infuriate Monk, and gaining new respect and admiration from his son. In truth, the real Frisco Fly was a man named Victor Grajna, who died several days earlier in a car accident which Joey Krenshaw discovered. Joey burned Grajna's car and got rid of the real Frisco Fly forever. Then Joey drugged Harold, took him up to the top of a high-rise building, and let Harold fall to what should have been his death had he not hit an awning and flagpole.
In "Mr. Monk and the Buried Treasure", Monk agrees to help Dr. Kroger's son Troy decipher what appears to be a treasure map (actually a map to a dead bank robber's body) in an attempt to once more outdo Harold, who has just given Dr. Kroger a wristwatch.
In the season six episode "Mr. Monk Joins a Cult", Dr. Kroger mentions that the Siblings of the Sun at one point tried to recruit Harold. According to Dr. Kroger, Harold was too smart for them.
In the season seven episode "Mr. Monk Gets Hypnotized", Harold tries hypnotic regression therapy with Dr. Lawrence Climan (Richard Schiff) which at first seems to cure him of his OCD. While investigating the "abduction" of actress Sally Larkin, Harold shows up at the crime scene and tells Monk about his new therapist, that he is over their feud, and also gives him Dr. Climan's business card. Seeing Harold so happy, Monk cannot concentrate on the case, so he decides to ignore the risks. He goes to Dr. Climan and comes out acting like a six-year-old. Though Monk eventually is able to snap himself out of his hypnotic state, hypnotherapy backfires on Harold when his feelings of euphoria lead him to take off all of his clothes in public, causing him to get arrested for indecent exposure (an incident that Monk witnesses).
Harold makes a brief cameo appearance in "Mr. Monk's 100th Case", for a small interview on a television special commemorating Monk's solving of his 100th case, which Harold derides. He also says that he thinks his new therapist is better than Monk's. It is implied by the next episode that Harold is referring to Dr. Climan.
Harold also appears in the season seven finale, "Mr. Monk Fights City Hall". Now serving on the San Francisco City Council, Harold initially votes against Adrian's motion to preserve the parking garage where Trudy was murdered, instead of demolishing it to build a children's playground. At first, Monk sways the a majority of the council to vote in his favor, but inadvertently tips the vote when he insults one of the other council members while exposing reporter Paul Crawford as a murderer. Harold also (thanks to an inadvertent slip from Natalie) learns the name of Monk's new therapist, Dr. Bell, and announces that he will also be seeing Dr. Bell in the future.
Harold has a cameo appearance in the season eight episode, "Mr. Monk is Someone Else", when Monk goes to Los Angeles masquerading as a mob hit man by the name of Frank DePalma. When Monk is having lunch at an outdoor cafe with Lenny Barlowe and Tommy G., a rollerblading Harold calls out to "Adrian". By a stroke of luck, Monk stays in character and tells Harold that he's made a mistake and if he is not careful, he'll be in Section D of the next day's paper (the obituary section). Then Monk shows himself off as a "tough guy" by shoving Harold away, who then apologizes saying that he thought "Adrian" was someone else.
In his final appearance, "Mr. Monk Goes to Group Therapy", Monk finds himself sharing group therapy sessions with Harold when his HMO refuses to compensate him for any more individual sessions with Dr. Bell. The two butt heads constantly, even to the point that when two of their other group members are killed under mysterious circumstances, Harold accuses Monk of being the killer. Both men are ultimately kidnapped by Xavier Danko, the real killer, and thrown into the trunk of his car together, where they both break down with claustrophobia and finally become friends: Harold admits that he has greatly exaggerated his own progress to goad Adrian, while Adrian admits that he envies Harold's relative success in going on with his life despite his many fears. The two men realize that they share many of the same problems, and even overcome their claustrophobia together when Monk convinces Harold to see the trunk as a protective space rather than a trap.
Afterwards, in an extraordinary gesture, Harold voluntarily transfers to another psychiatrist, to let Monk's "group sessions" with Dr. Bell be individual sessions after all.
Ambrose Monk 
|First appearance||"Mr. Monk and the Three Pies"|
|Last appearance||"Mr. Monk's 100th Case"
"Mr. Monk and the End - Part II (flashback only)
|Portrayed by||John Turturro
(2004, 2005, 2008)
|Occupation||Technical writer of instruction manuals and language dictionaries|
|Family||Jack Monk, Sr.
Jack Monk, Jr.
As stated by Adrian in "Mr. Monk and the Three Pies", Ambrose has not left the house since 1972, spending 32 years in the house. Adrian also reveals that Ambrose and their mother were in a state of catatonia after their father left. In fact, Ambrose did not even leave his room for an unspecified amount of time.
He can be seen in person in three episodes: "Mr. Monk and the Three Pies", "Mr. Monk Goes Home Again" and "Mr. Monk's 100th Case", as well as in home movies he spliced together himself during "Mr. Monk Is on the Air". He has a romantic interest in Natalie Teeger, Adrian's second assistant. Ambrose writes owner's manuals for many different consumer products in multiple languages which he taught himself (7 and 1/2 as of "Mr. Monk and the Three Pies"). The house is cluttered with his work, piles of newspapers (every single day for the past 32+ years), and filing cabinets that are stuffed with his father's mail spanning the entirety of his father's absence.
Ambrose blames himself for Trudy's death. At his request, Trudy went out to buy him cough medicine when she was murdered by a bomb planted under the front seat of her car. Guilt-ridden, Ambrose avoided all contact with Adrian for seven years after the incident.
Ever since their father left, Ambrose has been obsessed with the idea of his return, even to the point of preparing a dinner plate for him every night, just in case. Adrian feels differently, believing his father will never return. However, their father shows up at Ambrose's doorstep to leave a note. Adrian and Ambrose miss their father's appearance when while in an ambulance because they think he has been poisoned by a Neptune candy bar. Their father leaves a note, congratulating Ambrose on leaving the house. Ambrose has left the house three times: the first two times are in "Mr. Monk and the Three Pies", the first being when his next-door neighbor Pat van Ranken sets the house on fire, and the second to visit Trudy's grave, and the third one mentioned above in "Mr. Monk Goes Home Again".
In "Mr. Monk's 100th Case", he appears in a documentary about Adrian, and says his brother held the family together after Jack Monk left them. Both he and his mother became unable to deal with the outside world, and Adrian saved them. He greatly respects his brother's ability to cope with the outside world.
Even though Ambrose's last television appearance was in 2008, he continued to appear in the Monk novel series by Lee Goldberg. In Mr. Monk in Outer Space, he is shown to be a fan of the science fiction series Beyond Earth, and has even written a number of books about the series itself. It is also revealed that he is a good lip-reader, as he can read what a shooter on a surveillance tape is saying. Ambrose is also shown to have learned Pig Latin and the Dratch constructed language of Beyond Earth. Hence, he plays a big part in helping Adrian's investigation into the murder of Beyond Earth creator Conrad Stipe and later executive producer Kingston Mills. He identifies Mills's killer by reading his lips and creating a written translation.
He later appeared in the novel Mr. Monk Is Cleaned Out, when Adrian briefly moves in after he gets evicted from his apartment. This novel reveals that Ambrose wrote the instruction manual for the Triax tracking device that is utilized by alleged Ponzi schemer Bob Sebes, whom Adrian suspects as having killed three government witnesses about to testify against him for their parts in the scheme.
In the novel, Mr. Monk On the Road, Adrian, having found a balance in the world, knocks Ambrose out by drugging him with a sleeping pill placed in his birthday cake, then (with aid from Natalie) puts Ambrose in an RV. The novel serves to allow Adrian to help Ambrose get over his agoraphobia. At the end, Ambrose buys the RV that Adrian and Natalie rented for the trip. The novel also reveals that Ambrose became agoraphobic after he caught Hong Kong flu. As Adrian specifically resembles Sherlock Holmes, Ambrose is comparable to Sherlock's brother, Mycroft.
Starting in Mr. Monk On the Couch, Ambrose has a live-in assistant, Yuki Nakamura, introduced in Mr. Monk on the Road.
Kevin Dorfman 
Jarrad Paul as Kevin Dorfman
|First appearance||"Mr. Monk and the Paperboy"|
|Last appearance||"Mr. Monk and the Magician"
"Mr. Monk and the End - Part II (flashback only)
|Portrayed by||Jarrad Paul
(2004, 2005, 2007, 2009)
|Occupation||Accountant, Amateur Magician|
Vicky Salinas (ex-wife)
Sy Dorfman (uncle)
Kevin Dorfman (Jarrad Paul) is Monk's annoying, talkative upstairs neighbor. He appears in five episodes before he is killed by Karl Torini in "Mr. Monk and the Magician."
Kevin has a motor mouth, and every topic must be discussed in full detail. In "Mr. Monk and the Magician," Monk recalls a time when Kevin had a sore throat and "talked for two and a half hours about how much it hurt him to talk". As Monk and Natalie observe at Kevin's wake, this trait actually appears to be genetic. Natalie has a photo of Kevin on display, which she at first claims took over two hours to take because she wanted one where he was not talking, but upon noticing a skeptical look from Monk, admits to having Photoshopped.
Kevin first appears in "Mr. Monk and the Paperboy", where he wins $43 million in the lottery, although his "girlfriend" Vicki Salinas (Nicole DeHuff), a clerk at the nearby Stop-N-Go convenience store, tries to hide it from him with the objective of eventually getting it all. Her accomplice, the store's night manager, kills paperboy Nestor Alvarez while trying to steal newspapers that they think are Kevin's. Later, Vicki kills the accomplice by stabbing him with a cream soda bottle while he's making the store's night deposit. Vicki then tries killing Kevin by stopping their car at a certain point in the road and drugging him - which happens to be on a grade crossing right as the lights begin to flash and the gates begin to lower. Monk and Sharona arrive, having followed him thanks to a travel brochure, and after a struggle with Vicki, throw the switch at the crossover to shift the approaching train to the other track, just in the nick of time, sparing Kevin.
Although Kevin gets his money back, by the time he makes his next appearance in "Mr. Monk and the Game Show," he has lost it all to a number of serious misfortunes, including: bad investments, gold diggers, two wives, and a dishonest accountant. A CPA, he has two sisters and could recall all eight times he ate egg salad sandwiches. Kevin works in a coffee shop in Aspen, Colorado and in "Mr. Monk and the Game Show", he accompanied Monk when Adrian's father-in-law, Dwight Ellison, asked him to investigate a cheating problem on his game show Treasure Chest, which Dwight produces. Dwight is shown to suspect that TV host Roddy Lankman is feeding champion Val Birch the answers. According to Kevin, a pencil with Roddy's chew marks on it is a "collectible." The pencil proves handy, for when Monk and Kevin visit Val Birch's house, they find a pencil with identical chew marks.
In "Mr. Monk Is On the Air", when Monk is preparing to face Max Hudson on the radio, Kevin gives him some of his uncle's jokes for use as Monk prepares to accuse Max of murdering his wife Jeanette. It is also revealed that he had an uncle who was a comedian that knew Uncle Miltie.
An amateur magician, in "Mr. Monk and the Magician," Kevin is working as an accountant for professional magician, mentor, and close friend Karl Torini (Steve Valentine). While doing Torini's books, Kevin notices that the airlines are probably overcharging Torini, as for whatever reason, his receipts show that his equipment seems to weigh more when he comes back to the United States than it does when he leaves. Unknown to Kevin, Torini is secretly trafficking heroin for an Asian drug cartel. Fearing he might be caught, Torini and his assistant Tanya Adams kill Kevin on the night of his debut. They stage a phone call to make it seem like they are both in Reno, Nevada at the time (when Torini is actually hiding in the basement of the theater). After the show, Torini strangles and kills Kevin in his dressing room with a piece of piano wire, then leaves the building disguised as a maintenance man. Unfortunately, he is spotted by Monk (who is looking for Kevin) and accidentally gives himself away when he gestures in the direction of the dressing rooms with his middle two fingers together (Monk concludes that Torini was the so-called "maintenance man" when Torini does the same gesture at Kevin's funeral).
Despite the fact that Monk is always shown to be annoyed by Kevin, he is seen crying after Kevin's murder, hinting at a possible friendship they had.
Recurring characters and special appearances 
Jack Monk, Jr. 
|Jack Monk, Jr.|
|First appearance||"Mr. Monk Meets His Dad" (mentioned only)|
|Last appearance||"Mr. Monk's Other Brother"|
|Portrayed by||Steve Zahn
Jack Monk, Sr.
Jack Monk Jr. (Steve Zahn) is Adrian's half-brother. Jack Monk, Sr. left him and his mother Darlene after 10 years when their family was together.
Jack Jr. meets Adrian after he is arrested and imprisoned for attempting to sell cars that are not his own. He escapes from prison, but is framed for murdering Lindsey Bishop, one of the social workers at the prison, right afterwards. Jack goes to Adrian in hopes that Adrian can clear his name.
Jack Jr. appears to be a pathological liar, and often swears "hand to God" that he is telling the truth, when in actuality he is not. He also has an unusual obsession with the country of Paraguay. Adrian does not know what this may mean until he mentions this to Dr. Bell. Adrian becomes furious when he learns that Jack's obsession with Paraguay is because of Paraguay's new extradition laws, do not allow for extraditing individuals indicted for crimes other than murder. Adrian confronts Jack in front of Natalie, just as Jack is conning her into signing a check for an orphanage in Quebec.
Eventually, Adrian finds that Jack was framed by Daniel Reese, a guard at the prison who was Lindsey's boyfriend and the real killer. Jack is able to overcome Reese by running him over with Natalie's car. He goes back to prison, though Randy's handcuff key "went missing". He is mentioned in "Mr. Monk Meets His Dad". In that episode, the people at Tiger Bay happen to confuse Adrian for Jack Jr., because they do not know about Adrian and Ambrose, the other two sons of Jack Sr.
Adrian enjoys bonding with Jack, and even goes so far as to protect him by giving him the phony name of Jack Gretzky and claiming that Jack is his penpal (despite the name, Adrian has to tell others that Jack is not related to Canadian hockey player Wayne Gretzky).
Marci Maven 
|First appearance||"Mr. Monk and the TV Star"|
|Last appearance||"Mr. Monk's 100th Case"|
|Portrayed by||Sarah Silverman
(2004, 2007, 2008)
|Occupation||President of the Monk-o-Philes club|
Marci Maven (Sarah Silverman) is Monk's biggest fan and has made three appearances on the series. Marci first appears in "Mr. Monk and the TV Star" as a fan of Brad Terry, the star of the crime drama television series Crime Lab S.F.. As Monk and Sharona are first investigating the murder of Brad Terry's ex-wife Susan Malloy, Marci hands an envelope to Sharona, saying that it's a petition to get the old theme song back, since quite a lot of people hate the new theme song of Crime Lab S.F. However, Marci also dislikes the now-deceased Susan Malloy, since Susan only made one movie, called Frat Party Massacre, which Marci has watched several times. This makes Marci a primary suspect, and she is finally cornered by Stottlemeyer and Disher at the Crime Lab S.F. 100th episode cast party. At first, she confesses to murdering Brad's ex-wife, and Monk is convinced. But when Monk sees the renowned TV star lie to one of his scriptwriters about her script, he is convinced that Brad Terry is guilty. He confronts Marci about the matter, stating that she's protecting Brad because she knows he killed his ex-wife. After Brad is arrested, Marci is released from jail. A few nights later, Marci shows up at Monk's door convincing him that if he ever gets his own show, he should never change the theme song. (The theme song controversy surrounding Crime Lab S.F. is a parody of the controversy around the replacement of the original instrumental theme song for Monk with "It's a Jungle Out There".)
Marci returns in "Mr. Monk and His Biggest Fan". In this episode, she has started a website about Monk, and we see her digitally replacing Natalie's head with her own. The police show up, asking if Marci owns a dog named Otto, who apparently attacked and mauled to death Debbie Ringel, the wife of Marci's neighbor John Ringel. Marci shows them Otto's grave. When she shows up at Monk's apartment the next day, Natalie is able to shoo Marci out.
Later, as Linda Fusco bids for Stottlemeyer at the San Francisco Police Department's Bachelor Auction, Marci bids for Monk, resulting in a bidding match between her and Natalie which Marci wins after Natalie runs out of money. The next day, Marci shows Monk how much she loves him, wearing his old pants, serving his drink in his old glass, even showing him a diorama of them based on the season two episode "Mr. Monk and the Three Pies", while singing him a song on her guitar about him. She has even written fan-fiction centered around Monk, including one story entitled "Mr. Monk and the Dragon's Lair". Then Marci explains the problem she is dealing with: she knows Otto died three days before Mrs. Ringel was apparently "mauled", and the teeth marks on her body match Otto. Monk finds many clues that suggest that Otto was framed, and so Monk, Natalie, and Marci go to several lumberyards in the area. At John Ringel's lumberyard, they find clues that explain Otto's day-long disappearance of about two weeks earlier, the simple explanation being that Ringel made a pruning-type device that could make dog tooth marks on his wife's body after he murdered her.
Marci loses interest in Monk when Ringel shoots her during a hostage situation at his lumberyard. Although she has only been hit in the shoulder, she decides she is no longer interested in pursuing her interest in him. At the end of the episode she gives Monk a package holding all his stuff she took, saying her new obsession, F. Murray Abraham "wouldn't understand"--"May God have mercy on his soul," Monk tells Natalie. However, she reappears in "Mr. Monk's 100th Case", interviewed in a television show, reverting once again to her obsession with Monk. At one point in "Mr. Monk and His Biggest Fan", she stated, "I'm not crazy, just a fan". By a strange coincidence, Monk says the exact line to actress Christine Rapp (of The Cooper Clan) in "Mr. Monk's Favorite Show".
Jack Monk, Sr. 
|First appearance||"Mr. Monk Meets His Dad"|
|Last appearance||"Mr. Monk and the End - Part II"
|Portrayed by||Dan Hedaya
Jack Monk, Jr.
Jack Monk, Sr., played by Dan Hedaya, is Monk's father. He appears in the aptly named 2006 Christmas special "Mr. Monk Meets His Dad". Jack, the father of both Ambrose and Adrian Monk, abandoned his young family while running to pick up an order of Chinese food. Adrian was only eight years old and his father's abandonment is seemingly the catalyst for both Adrian and Ambrose's psychological illnesses. After leaving, Jack is not heard from for over forty years. During that time he fathered yet another son, 31 year old Jack Jr. whom Jack proudly brags about to his co-workers as a genius doctor, but later admits to Adrian's surprise that Jack Jr. is an unemployed buffoon who smokes marijuana all day and steals money from his wallet. Jack also makes an appearance, albeit an unnoticed one ("Mr. Monk Goes Home Again"), at Ambrose's door. He leaves Ambrose a congratulatory note on his exit from the house, though this was because he was being driven to the hospital in an ambulance after having eaten what he thought was a poisoned candy bar.
Little is known about Jack Monk's personal history. Adrian establishes in the above-mentioned episode that Jack wrote school textbooks as his career of choice, similar to Ambrose, and indicating some level of education. Not much explanation is provided for how he ends up in the state explored in "Mr. Monk Meets His Dad".
When Jack finally shows up in person, he is working for the Midland, Texas-based Tiger Bay Trucking Company and had been stopped in San Francisco for running a red light. He is arrested and placed in jail because he shoved a cop and resisted arrest. Initially, Adrian's reception to his father is icy and uninviting, but the two later reconcile over a road trip, where they suspiciously travel by the longer back roads. This is later revealed to be because of Jack's boss, Ben Glazer, who was trying to destroy evidence that would link him to the death of his partner, Kenneth Woods. The novel Mr. Monk in Outer Space reveals that Jack stopped to visit Ambrose after coming back to San Francisco.
Although the elder Monk is portrayed as eccentric, unpleasant, and erratic, he is also apparently quite intelligent, possibly implying that Ambrose and Adrian inherited at least some of their prodigious mental abilities from their father. He has a step-granddaughter named Molly Evans. Molly Evans is his granddaughter by marriage because his son Adrian's wife Trudy had a daughter before she met Adrian.
Gail Fleming 
Gail Fleming (Amy Sedaris) is Sharona's younger sister and an actress. She first appeared in "Mr. Monk and the Earthquake", where Sharona, Benjy, and Monk stay at her house after a magnitude 6.0 earthquake. Her second appearance is in "Mr. Monk Goes to the Theater". In this episode, she is framed by her understudy Jenna Ryan for stabbing actor Hal Duncan in a performance of the play Blood on the Moon during a preview performance prior to it heading to New York City. In "Earthquake" she remarks to Sharona that she thinks Sharona copies her by moving to San Francisco, buying the same purse, etc. Gail also makes an appearance in the novel Mr. Monk and the Two Assistants, where it is revealed that she is dating an accountant.
Cheryl Fleming 
Cheryl Fleming (Betty Buckley) is Sharona's and Gail's mother. When her husband, Douglas, died, she was left to raise her daughters alone. She visits Sharona in "Mr. Monk Goes to the Theater", just when Gail is framed for murder. She then begs Monk to take the case, which he eventually does, though reluctantly. Trying to impress her, Sharona tells her that she is Monk's partner, not his assistant/nurse. She also tells her she is dating a stock broker and that Benjy is on the honor roll.
Linda Fusco 
Linda Salvato Fusco (Sharon Lawrence) is Captain Stottlemeyer's girlfriend and a real estate dealer during season five and the beginning of the season six. The two began dating shortly after she hires Monk and Natalie to investigate damages to her car in "Mr. Monk, Private Eye", and she even sets Stottlemeyer up with a new apartment across the way from her own. The two continue to see one another, but their dates are often interrupted, postponed, or canceled as a result of Stottlemeyer's duties. For instance, in the episode "Mr. Monk and His Biggest Fan", Linda resorts to bidding on a date with Stottlemeyer at a bachelor auction just to get him alone as Marci Maven resorts to bidding on a date with Monk. However, their date is interrupted when Stottlemeyer realizes that John Ringel is a murder suspect and framed Marci's dead dog.
In "Mr. Monk and the Bad Girlfriend", Stottlemeyer's duties, and the fact that Linda has moved uptown to Richmond, means that she can only talk to him at 6:30 p.m. each night on webcam dates. They are planning on going to Hawaii. However, just before they leave for Hawaii, a masked intruder shoots Linda's former partner Sean Corcoran with a shotgun in an open house in front of two witnesses. Monk and Natalie are sent to Marin County to investigate, where Monk determines that the shooter had a house key. It isn't long before Monk and Natalie suspect Linda of being the killer, after Monk realizes that Linda has a strong motive, she knows how to use a shotgun (as he notices a photo of a younger Linda with her deceased grandfather on a hunting trip, carrying a 12 gauge shotgun), she is 5'7" (the killer's height as described by the witnesses), she has a house key, and she wears the very shade of lipstick one witness remembered the shooter as wearing.
Although Monk and Natalie believe Linda is the shooter, their problem is that they happen to be her alibi due to the webcam date from the night of the shooting, which they sat in on, and they have a hard time convincing Stottlemeyer or Randy that Linda is guilty. Furthermore, the distance is such that Linda could not have gone from the web date to the shooting scene in the time window provided, and this is confirmed when Monk and Natalie time the route on a motorcycle. But then they find a flower like one Linda was wearing on the night of the shooting.
To find evidence, Monk has Natalie lure Linda away from her house while he searches it. Monk finds a form for a rental truck, and a stashed barrel cleaner and bottle of gun oil, but Linda comes home while he's searching, and she attempts to seduce Monk, who quickly rushes out and drives away with Natalie.
Monk and Natalie catch Linda through a sting operation. Natalie crashes Stottlemeyer and Linda's going away party at the police station, and turns on Stottlemeyer's webcam. She summons everyone into the office, to show Monk apparently talking to them from Linda's bedroom. Monk turns on some Hawaiian music on the stereo, at which point Linda turns off the camera. However, Natalie opens the window to reveal that the music is still playing. Everyone follows the sound of the music downstairs to an impounded rental truck that was towed from Linda's street the day after the murder. Stottlemeyer then pushes up the rear door to find Monk sitting in a recreation of Linda's bedroom, that she had used for her alibi. Linda is arrested, and Stottlemeyer is left asking himself if the relationship was real or merely something she'd planned from the beginning so she could have a perfect alibi. At the end of the episode, he tosses something into the ocean. When Randy asks him what he just threw, Stottlemeyer replies "It's just a rock," suggesting that he was going to propose to Linda while in Hawaii.
Trevor Howe 
Trevor Howe (Frank John Hughes and David Lee Russek) is Sharona's ex-husband and Benjy's father from New Jersey. He appears in the episodes "Mr. Monk and the Sleeping Suspect" and "Mr. Monk and the Girl Who Cried Wolf". In "Mr. Monk and the Sleeping Suspect", he shows up at Sharona's house for Benjy's birthday, seemingly a "different man." Benjy is happy to have a father, which is one of the reasons Sharona decides to quit being Monk's assistant and move back to New Jersey with Trevor. She later discovers, however, that he got plane tickets to Detroit, where his rich uncle lives. Trevor admits to her that his reason for wanting to get back together with her was because his rich uncle had cut him off when he got divorced, and he wanted to get back together so that he would have access to his fortune. In his second appearance in the season three episode "Mr. Monk and the Girl Who Cried Wolf", Sharona asks Trevor to take Benjy when she becomes afraid she is losing her sanity, and hence crying wolf. In "Mr. Monk and the Red Herring", it is revealed that he has re-married Sharona. In the episode "Mr. Monk and Sharona", though, Sharona reveals that they have broken up for good.
Trevor also reappears in the novel Mr. Monk and the Two Assistants, having been framed for murder by the Los Angeles Police Department's private consultant Ian Ludlow, who frames five other people in addition to Natalie and Sharona for the murders he commits so that he can write his novels and meet his deadlines.
Trudy "T. K." Jensen 
Trudy "T. K." Jensen Stottlemeyer (Virginia Madsen) is Captain Stottlemeyer's love interest in season eight. She initially appears in a three-episode story arc beginning with "Happy Birthday, Mr. Monk". She works for a magazine similar to Consumer Reports and is covering the debut of the new LaserVac self-cleaning vacuum. Throughout the episode, Leland tries to figure out what her nickname T.K. stands for, but when he finds out that her first name is Trudy, he takes concern and suggests that they stick with calling her T.K. In the episode "Mr. Monk is the Best Man", she marries Stottlemeyer after they have been dating for six months. Their wedding is almost thwarted by T.K.'s maid of honor, Stephanie Briggs, a former ecoterrorist who makes several threats against them, but later turns out to have been trying to retrieve the Kahr K9 handgun she used to kill fellow ecoterrorist Martin Kettering. Monk is shown to have been fine with T.K.'s name, believing that everyone should have a Trudy in their life.
Karen Stottlemeyer 
Karen Stottlemeyer (Glenne Headly) is Leland's environmentally conscious wife during the first four seasons and the mother of their two children, Jared and Max. She spends much of her time filming unscripted documentaries.
Karen first appeared in "Mr. Monk and the Very Very Old Man", where she begs Leland to investigate the death of Miles Holling, the oldest man in the world. Karen's documentary about Miles Holling, Miles Holling: The Human Time Machine, provides several clues for Monk and Leland about the man's death. The episode also establishes that their marriage is not necessarily stable, to such an extent that when Randy informs Leland that Karen wants to see him, Leland panics and has Randy keep her occupied while he gets his office reorganized (hanging a dreamcatcher from his lamp, hiding some of his personal junk, and installing a waterfall (that he fills with coffee)).
Karen is also strongly against the use of guns. In "Mr. Monk and the Very Very Old Man", she gasps and is visibly uncomfortable when Randy tries distracting her by showing her his sidearm. Additionally, she is under the impression that her husband never uses a gun, therefore, Leland has to hide his sidearm in a desk drawer whenever Karen visits. In "Mr. Monk and the Captain's Marriage," Monk recalls to Natalie a weekend where Leland went on a hunting trip, while Karen stayed behind to organize a gun control rally.
Karen later appears in "Mr. Monk and the Captain's Wife", where she is temporarily put in a coma when Evan Coker, trying to recover a pistol stashed in his repossessed car, shoots the driver of the tow truck carrying the car, causing the truck to swerve into Karen's van.
In "Mr. Monk Gets Fired", Karen is seen filming a documentary of life in the San Francisco Police Department's Homicide Division, including many moments of Commissioner Brooks's anger and Paul Harley's arrest. In "Mr. Monk and the Captain's Marriage", Sergeant Ryan Sharkey, Jr. claims to Leland that he is having an affair with Karen, provoking Leland into punching him. To find the truth, Leland sends Monk and Natalie to stalk Karen. They find that while Karen is seeing someone, it is not Ryan Sharkey, but rather a divorce lawyer. She has a sister.
Karen is mentioned, but does not appear, in "Mr. Monk Goes to a Rock Concert". She calls Leland saying that Jared has skipped school and most likely has gone to a rock concert where Kris Kedder is performing, which leads Leland, Monk, and Natalie to go to the San Francisco Band Jam.
Mitch Teeger 
Lieutenant Commander Mitch Teeger (1971–1998) is Natalie's late husband who was a fighter pilot in the United States Navy. He died in 1998 in the Kosovo War. He allegedly abandoned his men and took their supplies, but Natalie does not believe the reports, as revealed by Natalie in "Mr. Monk and the Election". Much of what is known about Mitch is known through the Monk novel series by Lee Goldberg.
In the novel Mr. Monk Goes to Hawaii, Natalie reveals that Mitch died two days before his 27th birthday, which would place his birth date in 1971, and would make him 41 if he were still alive today. The two of them also once traveled to Mexico to elope, much to the horror of Natalie's parents. It is also mentioned in Mr. Monk Goes to the Firehouse, and elaborated upon in Mr. Monk is Miserable, that Natalie and Mitch eloped to Paris. When Natalie later sees Paris in that novel, she claims it is a different Paris from the one she and Mitch had gone to.
In the season eight episode "Mr. Monk and the Voodoo Curse", it is revealed that Natalie's superstitions about voodoo result from when she and Mitch lived on a military base in South Carolina. She met a voodoo priestess who predicted Mitch's death a few days before it actually happened.
The episode "Mr. Monk and the Red Herring" establishes that he always wanted to be an astronaut, and that he'd received a letter from NASA about being accepted into their training program a few days after he died.
The episode "Mr. Monk and the Three Julies" and the novel Mr. Monk and the Dirty Cop that Mitch taught Natalie how to shoot a gun, though Natalie's firearms skill called into question in "Mr. Monk on Wheels". When Natalie grabs biotechnician Sarah Longson's Walther PPK handgun to force her to surrender, she whirls around so quickly that she accidentally discharges a bullet into Monk's right leg). Natalie brings this up in Mr. Monk and the Dirty Cop when holding crooked Intertect CEO Nick Slade up at gunpoint.
In the season five episode "Mr. Monk and the Class Reunion", when Monk is mentioning that he thinks he can handle his 25th college reunion on his own, Natalie suggests that she should accompany him, considering how he last met many of these students when he was with Trudy, and she remembers how she missed Mitch the most when going to parties or visiting friends after his death.
In the season seven premiere "Mr. Monk Buys a House", it is presumed that Mitch also taught Natalie how to use Morse code. When Monk, Natalie, Stottlemeyer, and Disher visit Cassie Drake's house, and Stottlemeyer and Disher start tapping messages to each other in Morse code on the door, Natalie chastises them, hinting that Mitch taught her Morse code. This comes in handy later in the episode: when Monk and Natalie are taken hostage by "Honest" Jake Phillips (Brad Garrett), Natalie sends up smoke signals in Morse code through the fireplace to call for help, due to a lack of other forms of available communication.
In Mr. Monk and the Two Assistants, Natalie mentions that she and Monk actually have a lot in common. Both have lost spouses to violent deaths (Trudy to a car bomb, Mitch to a plane crash), and in both cases they were affected heavily and only saved thanks to someone else. In Monk's case, he hires Sharona and Stottlemeyer hires him as a consultant; in Natalie's case, Julie saved her.
The choice of Mitch as the first name of Natalie's late husband is a possible in-joke reference to the 1998 film Dirty Work; in that film, Traylor Howard plays the love interest of protagonist Mitch Weaver. It should be noted that although Mitch is said to have died in the Kosovo War, in reality, the United States did not have any fatalities at all, either as the result of military combat or accidents.
Mitch is portrayed by Monk co-producer Doug Nabors, and can be seen in Natalie's pictures in her house and her car.
Steven Albright 
Lieutenant Steven Albright (Casper Van Dien) is a lieutenant in the United States Navy and Mitch Teeger's oldest friend. In the season seven episode "Mr. Monk is Underwater", where he is introduced, he asks for Monk's help with the murder of Lieutenant Commander Jason Pierce while serving aboard the U.S.S. Seattle, a Los Angeles class submarine. Though he and Natalie are strongly attracted to each other, she is hesitant because of her lingering feelings for Mitch. He also saves the two from being drowned by Commander Nathan Whitaker, the person who killed Pierce. However, Steven reappears in the series finale, "Mr. Monk and the End", in which he and Natalie have been dating for a long time, and Natalie is planning to introduce him to Julie.
Warrick Tennyson 
|First appearance||"Mr. Monk Goes to Jail" (Mentioned Only)|
|Last appearance||"Mr. Monk Takes Manhattan"|
|Portrayed by||Frank Collison (2004)|
Warrick Tennyson was a career criminal and explosives expert who was hired to build the bomb in 1997 which killed Trudy (Monk's wife). Dale the Whale tells Monk that Tennyson was involved in the murder, in "Mr. Monk Goes to Jail". He tells Monk he can find Tennyson in New York. Monk goes to New York in the next episode, "Mr. Monk Takes Manhattan", in hope of answers, but finds that Tennyson is dying of heart disease and kidney failure. Because he’s being questioned in connection with a Federal racketeering case, the District Attorney is not letting anyone else see him. The only way for Monk to get access to Tennyson is to solve the recent murder of the Latvian Ambassador.
Having cracked the case, Monk's party is allowed to visit Tennyson (Collison) on his deathbed. Tennyson remembers being hired by a man to build the bomb that killed Trudy. When asked, he says he does not know the name or the description of the man that hired him, since it was dark when they met, and it looks like Tennyson is a dead end. But Tennyson remembers one vital clue: the man had six fingers on his right hand.
Monk asks for a few moments alone with Tennyson. When the others are gone, Tennyson asks for forgiveness, but Monk cannot bring himself to give it. He turns off Tennyson's morphine drip. But a few tense moments later, he turns it back on, saying "[T]his is Trudy, the woman you killed, turning it back on".
Frank Nunn 
|First appearance||"Mr. Monk Takes Manhattan" (Mentioned Only)|
|Last appearance||"Mr. Monk Is On the Run (Part One)"
"Mr. Monk and the End" (Flashback Only)
|Portrayed by||Courtney Gains (2008)|
Frank Nunn was a career criminal who was hired by a mysterious figure known as "The Judge" to assassinate Trudy Monk. Nunn hired Warrick Tennyson, an explosives expert, to build and plant the bomb, while Nunn detonated it with a cellular phone. Twelve years later, he was hired to build another bomb, as part of a scheme by Dale Biederbeck, and plant it in the back of a car meant to be ridden by the Governor of California and his wife during his hometown's bicentennial parade. Unknown to Monk, Nunn is also a pawn in a related scheme to frame him for murder and incapacitate him. In "Mr. Monk Takes Manhattan", Warrick Tennyson tells Monk that he was hired to build the bomb which killed Trudy, by a six-fingered man. This six-fingered man detonated the bomb from a distance with a cellular phone.
The season six finale "Mr. Monk Is On the Run" continues the investigation when Monk and Natalie are called to the scene of an electronics store robbery. Several items have been stolen that when combined, can be used to build a bomb, and a crowbar dropped by the thief bears fingerprints from a man with six fingers on his right hand. Monk believes this to be the same man who murdered Trudy.
A note is also left behind which reads: "To Force Heaven Mars Shall Have A New Angel". When Monk decodes the message as saying "247 Marshall Avenue, Angel, California", he goes there alone, taking along his old police-issue pistol. There, he meets Frank Nunn, who recognizes Monk as "the cop with the wife". Frank Nunn shows no remorse. In rage, Monk lunges at him and the two engage in a violent brawl, during which Monk repeatedly kicks and punches Nunn before drawing his pistol and demanding to know who hired him. Before Nunn can answer, he is shot dead by a corrupt local sheriff, John Rollins.
Later he appears to be of some use, as the police find papers in Frank Nunn's apartment connecting Trudy's murder with a mysterious figure known as "The Judge".
Judge Ethan Rickover 
Judge Ethan Rickover (Craig T. Nelson) is a respected former college professor turned federal judge. Prior to his appointment as a judge, and Trudy meeting Adrian, Rickover has an extramarital affair with Trudy. The affair resulted in Trudy becoming pregnant with his child. After the baby was born, Rickover covered up the illegitimate child by telling Wendy Stroud, the midwife, to tell Trudy that her baby died about nine minutes after birth and to then put the child up for adoption.
Fourteen years later, in 1997, Rickover is nominated as federal judge. Stroud comes forward claiming she has "found God" and can no longer live with her guilty conscience over what she did. Stround says she will reveal the truth about his and Trudy's illegitimate child, which would ruin his confirmation chances. Rickover realizes any information regarding these events could be potentially damaging to his political career and has Stroud killed to keep her quiet, burying her body in his backyard.
Around the same time, Rickover hires bomber Frank Nunn to plant a bomb in Trudy's car. Trudy has already suspected that Rickover was involved in Wendy Stroud's death after she read about it in the newspaper. When Trudy is subsequently killed, it is impossible to connect either her death or Stroud's death to Rickover, allowing him to have a prosperous career as a judge. Twelve years later, in 2009, Rickover has come far in his career, having been recently nominated for the California Supreme Court. He still lives in the same house because he knows that Wendy Stroud's body is buried in the yard, marked by a sundial.
Dr. Malcolm Nash (Ed Begley, Jr.), the director of the clinic where Stroud worked, discovers the truth about Trudy's child while digitizing the records from old paper records to computer files. Coincidentally, Nash is earlier questioned by Monk and Stottlemeyer when they got the call that Trudy had been killed. Nash calls Rickover, blackmailing him for information. Panicking, Rickover hires a different professional hit man, Joey Kazarinski, to kill Dr. Nash.
Monk gets involved in the investigation following Dr. Nash's death and is able to uncover evidence at the crime scene linking back to Kazarinski. Rickover finds out about this when Stottlemeyer comes over to his house to sign a warrant to search Kazarinki's premises. Fearing that Monk's involvement in the investigation may ultimately lead back to him, Rickover orders Kazarinski to kill Monk as well. Kazarinski poisons Monk's wipes with a ricin-based synthetic poison that will kill him in a period of two or three days. When Kazarinksi gets hit by a train and dies while being chased by Stottlemeyer through a yard, Rickover thinks himself to be cleared of any suspicion. Unbeknownst to him, the day before Trudy was killed, she made a video message to Adrian, explaining how Rickover wanted to meet her in that parking garage, and also mentioning the secret affair.
Having just found out about the video, Monk confronts Rickover and informs him that he knows he was behind Trudy's death, although he has no other evidence to back this up. Eventually, Monk realizes why Rickover refused to move away from his longtime house and confronts Rickover again in his yard as he is returning home, forcing Rickover at gunpoint to dig up Wendy Stroud's body. The body is eventually found, with both Monk and the police present at the scene, and Rickover confesses to the murders of Wendy Stroud and Trudy. Deciding not to kill Rickover, Monk puts the gun on the sundial in Rickover's garden, which Rickover then picks up and holds to his own head, saying "Take care of her," before pulling the trigger. Because he is the only person left to know that Trudy's child is still alive, no one is able to figure out what exactly he meant by his final statement. Eventually, Monk finds an article, dated the same day that Trudy's illegitimate child was born, detailing how Wendy Stroud saved a child. Adrian is then able to locate his stepdaughter. Rickover first appeared in "Mr. Monk and the End - Part I" and later in "Mr. Monk and the End - Part II".
Molly Evans 
Molly Evans (Alona Tal) is the illegitimate daughter that Trudy had in her affair with Rickover. She was born January 2, 1983, but was taken from her mother immediately after birth by Wendy Stroud, the midwife, at the behest of Rickover; Trudy was told that the baby had died nine minutes after birth. Stroud then claimed to have found Molly abandoned at a playground and took her to an orphanage. She is eventually adopted into a family and becomes a movie critic for the fictional East Bay Chronicle.
Monk initially believes Molly to be dead, based on the information given to him by Trudy in her video to him. After finding evidence to suggest otherwise, Monk discovers that she is still alive. Monk decides to meet Molly, the two of them quickly bonding and forming a friendship. According to Monk, Molly seems to be similar to Trudy not only in appearance, but also in her mannerisms. With Molly filling the void that Trudy's death left in his life, Monk initially decides to retire from detective work. However, when Molly reminds Monk that there are other people out there who are going through the same things that he's gone through and that they need his help, he decides to resume his career as a detective. Molly appeared only in "Mr. Monk and the End - Part II".
Jared Stottlemeyer 
Jared Stottlemeyer is Leland's eldest son who appears in four episodes, always played by different actors to show his aging.
In his first appearance, in "Mr. Monk Goes to the Ballgame", Sharona gets angry at Leland because Jared is too old to be in little league baseball, something Leland is forced to admit. This implies that at one point Jared had to repeat a grade. He was portrayed by Cameron Cush in this episode.
In "Mr. Monk and the Captain's Wife", Monk is forced to take Jared and his brother to lunch because Karen is hospitalized after a tow truck driver is shot and killed by a sniper, causing the truck to veer into Karen's oncoming van, and because Leland is working the homicide case. In this episode, he was portrayed by Jesse James.
The relationship between Leland and Jared was a little difficult after the events of "Mr. Monk and the Captain's Marriage", with Leland divorcing Karen, leaving him estranged from them. This becomes a major plot point in the season 5 episode "Mr. Monk Goes to a Rock Concert". In this episode, he skips school to attend a local music festival, forcing Leland to head there to find him, accompanied by Monk and Natalie. Leland's and Jared's relationship is evidently strained, since the only photo Leland has for the security guards at the main entrance to the grounds is a photo from a trip to Cabo San Lucas that obviously is several years old. Later on, Monk and Natalie find the dead body of a roadie, Stork Murray, in a port-a-potty. Assisted by Stork's girlfriend Kendra Frank (Tamara Feldman), Monk and Natalie investigate and discover evidence incriminating pop singer Kris Kedder (Brad Hunt) in the murder. The clue that allows Monk and Natalie to focus on Kedder is Jared's knowledge of guitar strings, and the fact that the string came from a twelve-string guitar - of which Kedder is the only person on the grounds to use one. As they move to capture an incriminating beachball with air from Kedder's asthma inhaler, the ball lands in the scaffolding for one of the loudspeakers. Jared is about to throw it to his father when Kedder comes up, leaving Jared with the split-decision to either let a killer get away or standing up to his father. After a few tense moments, he throws the ball to Leland, and Randy arrests Kedder. At the end of the episode, Jared and Leland stop at a photo booth so that Leland will have updated photos for the next time he takes off.
He makes a brief appearance in "Mr. Monk Is the Best Man", played by Matthew Scott Hill.
